Kris Humphries -- How I Knew Kim Kardashian Cheated on Me with Kanye West

EXCLUSIVE

Kris Humphries told his ex, Myla Sinanaj ... he KNEW Kim Kardashian hooked up with Kanye West because he was mysteriously absent from the big wedding ... sources close to Myla tell TMZ.

We're told Kris groused to Myla about how Kris Jenner suspiciously referred to Kanye as "a close family friend" -- someone Kim knew for a long time. Kris H told Myla, "If he was such a close family friend, why wasn't he invited to the wedding?"

We're told Kris confided in Myla he "felt played" by the whole thing and was genuinely devastated when news of Kim's new relationship broke.

Our sources say Kris was with Myla the day Kanye's song about dating Kim (and dissing Kris) was released -- and Kris was "visibly upset."
